I took my town’s map from OSM and did all the steps of converting it to something that was readable by Mapsource (used Mkgmap to convert and Mapset Toolkit to install). It went perfectly smooth. No problems at all.
The problem, however, is that the map can’t be downloaded, because there is “no map selected”. I think this is because the map is not split into regions that can be selected with the map tool and then downloaded into the GPS.
I tried using the mkgmap splitter tool, but the map is so small that it basically doesn’t change anything.
Any ideas on how I should proceed?
